Abstract (en)

Aspects of the present disclosure are directed to method, circuits, and apparatuses for power conversion. In an example embodiment, an apparatus includes a boost converter having a current loop affected by at least one compensation correction parameter and variation in an inductance of the current loop. The apparatus also includes a power factor correction means, including a circuit, configured and arranged to adaptively modify the compensation correction parameter based on variation in the inductance of the current loop.
